IMPROVEMENT IN GRINDING ATTACHMENT FORfi ARDI-NG-MACHINES.

The schedule'referred to in these Letters Patent and making part of the same and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanyingdrawing forming part of this specification.

This invention relates'to the application tonardingmachines of an attachment for imparting motion to the carding-cylinders in the direction opposite to their working motion, as is required for grinding the cards, by meansof the main driving-belt while working on the loose pulleyof the main card-shaft, and'wit-hout .thelabor and delay involved in the present practice of lengthening and crossing the driving-belt.

Figure 1 is a side elevation of an attachment such. asI propose to use.

Figure 2 represents the same in end elevation, and aside elevation of a carding-machine, the latter in dotted lines, showing the relation of the attachment to the carding-machine when the latter is driven from below.

Similar letters ofrcference indicate corresponding parts. j

A is a counter-shaft, provided with a double fast pulley,'B B, and either with or without a dividing rim, 0. This shaft is represented in this instance as mounted in a stand, D, with a dovetailed groove on the bottom, by which it may be detachably connected to the floor, by the side of the carding-machine, by a plate, E, attached thereto, and fitted to engage in the said groove and hold the stand, which may be provided with a set-screw, F, to confine the parts firmly together. d

This is the proposed arrangement for use when the carding-machines are driven by belts from below; but, whendriven from above, as is often the case, I propose to adopt any arrangementof stand by which the said counter-shattcan be properly supported in relation to the driving-belt, so that the latter, in running to the loose pulley on the cylinder-shaft, will impart motion .to the pulley B in the same manner as when placed below, as here shown, the main belt G being represented as hearing against thesaid pulley at H, and imparting a motion to it in the direction opposite to that in which the loose pulley on the cardcylinder moves, on which the said main belt is worklnll V l 1 is a short belt placed on the other part, B, of the pulley of the shaft A, and on the fixed pulley of the card-cylinder, giving the requisite motion to the latter, and from this the'top card M may be briveu back-ward by its connection with the main card by a belt.

' The dofi'er P may be driven by a belt, a, from a small fast pulley, N, on the shaft A.

Instead of driving the shaft A and pulley B B by the contact of the main belt, as at H, I may place a pulley on the loose pulley of the cylinder-shaft temporarily, by clamping to the side thereof, and run a crossed belt therefrom to the pulley of the shaft A.

I propose to attach a plate, E, to the floor at the side of each machine, for the ready connection of this apparatus at any time it may be required to grind the cards. Or, in case the same is to be connected'above, as aforesaid, I make like provisionthereat.

It will be seen that, by the employment of an attachment of this character, and one, or, at most, two short belts, the adjustment for reversing the motion of the card-cylinders may be made at any time in the most ready manner.

Having thus described my inyention,

I claim as new and desire to secure by Letters Patent- The application to carding-machines of a reversing attachment, consisting of a counter-shaft and one or more pulleys adapted for connection either to the floor below the shaft of the card-cylinder, or to the frame thereof, or other support at the side of the machine, and to have motion imparted to it by the contact of the main belt, when running on the loose pulley of said cylinder, or by a crossed belt working on a pulley temporarily attached to the said loose pulley, and connected with the fixed pulley of the carding-machine, or with the top cards, by belts, substantially as specified.

The abovespecification of my invention signed by me this 11th d. y of March, 1870.
